This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.

Be warned:

If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

Correct.

https://en.m.wikipedia.org/wiki/Novikov_self-consistency_principle

Within that framework, HP timetravel is self-consistent and, say, Back to the Future and others of that type aren't.

Very well shown in Rick & Morty snake timetravel episode. The snakes do the inconsistent time-travel and Rick only does consistent.
